To all whom, t may concern:

Be it known that I, FLORIAN M. PFLUGER, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Beer-Taps, of which the following is a speciiication.

My invention is a beer-tap, and consists of a two-part casing and a certain arrangement of packings in connection with said casing and with the tapping-tube and certain means of connecting the casing to a tap-bung, as fully set forth hereinafter and as illustrated in the accompanying drawings, in which- Figure l is a sectional elevation illustrating my im roved beer-tap applied to a tapbung of a arrel. Fig. 2 isa section on the line 2 2, Fig. l. Fig. 3 is a perspective view of the upper section of thecasing, Fig. 4, a detached view of the tube or sleeve interposed between the packings.

The tap-tube A can be applied through the two-part casing B, the lower part 2 of said casing having ianged projections 3, by

means of which it may be teirporarily con-` nected to a suitable tap-bung which may be constructed in any desired manner allowing of such attachment. The upper section 8 of the casing B has a tapering seat for a packing-sleeve 4, surrounding the tap-tube A, while the lower section 2 has a tapering seat for a packing-sleeve 5, the outer end of which may bear against the top of the tapbung, and between the two packings 4 and 5 there is a chamber to which air may be admitted through a suitable inlet 6, closed against back pressure by a flexible valve 7, as usual. With these parts I combine any suitable means whereby the two sections of the casing may be brought closer together or se arated to thereby vary the pressure upon t e packings-as, for instance, a screw-ring D, the threads of which are adapted to reverse threads upon the two sections of the casing, so that by turning the ring in one direction the sections will be brought together and by turning it in another direction they will be separated. The compression of the two packings by bringing the rings together results from an interposed sleeve E in Contact with both packings.

downward into the barrel, and an air-channel 9 is therefore provided. This is best secured by means of a collar F, larger in diameter than the pipe A and itting within the packing 5 and with a iiange bearing on the top of v the packing, so that the compression of the packing 5 does not close the channel 9l ing slots 13 in the flange 12, adapted to receive a rib or ribs 14 on the section 2 of the casing.

To prevent the escape of air between lthe two parts of the casing, a packing 17 is interposed between the iiange l2 and the ring D and between the top of the section 2 of the casing and a shoulder 19 of the section 8. It therefore results that when the two sections are brought together the packing 17 will be compressed to form an air-tight joint.

Without limiting myself to the precise construction and arrangement of parts shown, I claiml. The combination of the tap-tube and a two-part casing, the lower part adapted for application to a bung, an air-inlet to the easing, means for packing the joint between the casing and tube above the air-inlet, a pack.- ing within the lowerpart of the casing, and means Within the casing for forcing the packing downward to close the joint between the bung and casing, substantially as set forth.

2. The combination of the tap-tube and a two-part casing, the lower part adapted for application to a bung, an air-inlet to the casing, packings surrounding' the tube above and below the air-inlet, one of said packings being in each part of the casing, a sleeve eX- tending between the packings, and means for carrying the two parts of the casing to and from each other, substantially as set forth.

3. The combination of the tap-tube and a two-part casing, the lower part adapted for application to a bung, an air-inlet to the casing, packings surrounding the tube above and below the air-inlet, one of said ackings being in each part of the casing, a s eeve eX- tending between the packings, and a screw- It is desirable to permit the air to flow ring adapted to reverse threads on the two from the chamber between the packings parts of the`casing, substantially as set forth.

4. The combination of the tap-tube and a two-part casing, the lower part adapted for application to a bung, an air-inlet to the casing7 packings surrounding the tube above and below the air-inlet, one of said ackings being in each part of the casing, a s eeve extending between the packings, a screw-ring adapted to reverse threads on the two parts of the casing, and a packing between said parts and said ring, substantially'as set forth.

5. The combination of the tap-tube and a part casing, the lower part provided with iianged projections for connection 'with a bung, an air-inlet, packings within the Lipper and lower parts of the casing to Close respectively the; j'oint between the tube and casing above thejfair-inlet and the joint between the lower section of the casing and the bung, a sleeve extending between said packings, and means for carrying the parts of the casing toward each other to compress the packings, substantially as set forth.

two-part casing, means for carrying the parts of said casing-to and from each other, each part having a tapering seat for a packing, packings bearing on said seats, and means for pressing said packings against their seats as the parts of the casing are carried toward each other, substantially as set forth, 4

8. The combination of the tap-pipe A, casing-section 2, having an air-inlet and tapering seat for a packing, casing-section 8 sliding independently of the section 2 but incapable of turning independently thereof, means for carrying the casings to andfrom each other, a packing in each section of the casing7 and a bearing member interposed between the packings, substantially as se forth.

9. The combination of the two-part reversely-threaded casing-sections, a ring D, a packing interposed between the sections and the ring, packings 4 and 5, and a sleeve interposed between said packings7 substantially as set forth.

10. A tap com )rising a casing adaptedfor insertion'in the ung-hole of a cask, means for locking said casing in said cask, a discharge-pipe in said casing, packings for the joints between said casing and said dischargepipe and between said casing and the cask, and means connecting said packings whereby both said .packings may be tightened simultaneously.

11. A tap comprising a casing adapted for insertion in the bung-hole of a cask, a disv charge-pipe extending through said casing, packings for the joints betweensaid casing and said discharge-pipe and between said casing and the cask, and means connecting said packings whereby both said packings may be tightened simultaneously.

12. A tap comprising a casing adapted for insertion in the bung-hole of a Cask, a discharge-pipe extending through said casing,

packings for the joints between said casing 7. The combination of the tap-tube and and said discharge-pipe and betweensaid casing and said cask, means for tightening one of said packings and a member for transmitting the tightening movement of said means to tighten the other of said packings. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
